Systems and methods for estimating a parameter for a 3D model

A system operable to determine a parameter for a 3D computer model of a three-dimensional object, comprising:

• a processing unit having a plurality of channels;
• and
• a program storage device carrying instructions that, when executed, cause the processing unit to:
• receive surface data representing a contoured surface of a three dimensional object into memory of a computer having a processing unit, said surface data generated by a data acquisition device capable of generating the surface data;
• receive a reference signal into the memory of the processing unit, the reference signal based on the surface property of the object related to the data generated by the data acquisition device;
• estimate a noise level associated with the data with the processing unit;
• identify a plurality of lines within the surface data with the processing unit, the plurality of lines each defining one of a breakline or a boundary of the contoured surface;
• segment the surface data along the line data with the processing unit into a plurality of line data kernels representing the plurality of lines and a plurality of surface data kernels representing a plurality of non-coplanar surfaces separated by the plurality of lines;
• compute a first set of parameters with the processing unit for a directional filter based on the estimated noise level;
• compute a second set of parameters with the processing unit for a surface filter based on the estimated noise level;
• apply the directional filter to each of the plurality of line data kernels in a direction of the line data for each of the line data kernels using a first channel of the processing unit operating in parallel to simultaneously remove noise from each the plurality of line data kernels;
• apply the surface filter to each of the plurality of surface data kernels using a second channel of the processing unit operating in parallel to the channel of the processing unit to simultaneously remove noise from each of the plurality of surface data kernels;
• and
• generate refined surface data representing the contoured surface of the three dimensional object from the filtered line data kernels and the filtered surface data kernels by combining the separately filtered line data kernels and the separately filtered surface data kernels with the processing unit.
